Lasik Surgery - a personal view

Lasik Surgery - a personal view

I have noticed that more people I work with are talking about, or undergoing, the Lasik vision correction procedure.  I don't know really know why Lasik has suddenly become more popular in my company, but I do know that there are a number of rumors about Lasik that I am not sure are true.  Let me just talk about my long term experience with Lasik.

It has been more than eight years since I had the Lasik procedure, so I was one of the early and brave pioneers!  Perhaps I wasn't that brave when considering Lasik, for my vision in each eye was worse than -9.  Even now, Lasik physicians consider that a very strong case and do caution prospective clients that the Lasik process will likely improve their vision, but may not eliminate the total need for glasses.

The Lasik operation itself had mild pressure and some unusual feelings, but no real discomfort or pain.  This is still true in modern Lasik procedures, and hopefully they are even better at keeping the client comfortable.  I do notice that now Lasik physicians also give a mild sedative mainly for psychological reasons, which I think I would have appreciated back then.

Two or three days after the Lasik operation I was astounded to find I had VERY clear vision in each eye, at least 20/20.  Considering my previous prescription, you can imagine how fervently I thanked my Lasik physician.  However, I did also have temporary symptoms of considerable dryness in each eye (which was helped by eye drops), and also halos around lights at night.

A few months after the Lasik procedure I noticed my vision changing a bit, though very slightly.  The best way I can describe it is that the crisp edges no longer looked exceedingly crisp, but each object still seemed to be in focus.  At my one year Lasik correction anniversary my physician said that one eye was still at 20/20, but the other had changed slightly to 20/40.  However, I was still a great statistic for the Lasik correction procedure, and we were both still happy with the results.

In the years between the original Lasik procedure and now, my vision is still 20/20 in one eye and 20/40 in the other.  I do have a pair of glasses and one contact lens for that eye, but rarely bother with them unless I am doing something like watching a movie.  My long track record after the Lasik procedure has given hope to a number of other people in my office.  I do want to say though that I was over 35 when I had the operation, and my Lasik physician said that the stability of my eyes and my age were good indicators that the Lasik results would be long term.

I hope this encourages people with bad vision to talk to a local Lasik physician about scheduling a Lasik procedure.  Find a physician that has a good track record, and one that you trust, and I hope that your long term Lasik results will be as good as mine!

What Happens After the Lasik Procedure?

What Happens After the Lasik Procedure?

After you are fully prepared, the Lasik procedure takes less than fifteen minutes to complete for both eyes.  This will seem a remarkably short time to have a permanent change to your vision, and in this regard Lasik seems almost too good to be true.  In addition, most Lasik patients notice improved vision immediately or within a few hours after the Lasik procedure has been performed.

This does not mean that you should expect to walk out of the Lasik clinic with perfect vision and without any need to treat your eyes carefully for the next several days.  It also means that some Lasik patients will need more time to see the total results for the Lasik procedure, sometimes as much as six months for their vision to stabilize permanently.  Anticipate good vision, and take the time and care for the operation to produce its best result.

Usually the Lasik physician will give the post-procedure patient a protective shield for their eyes.  This should be worn as long as the physician specifies, and usually only at night for one or two nights.  He may also recommend sunglasses during the day if you experience sensitivity to light after the Lasik procedure is done.  Discuss these options in detail at the Lasik center before the operation, so you know how to best take care of your eyes.

Many patients at the Lasik centers often get eye drops to keep their eyes moist for some time after the Lasik procedure is done.  Again, this varies by patient and by physician, so ask about your particular situation, especially if you are prone to eye dryness on an occasional basis even before the Lasik procedure.  Also, it might be helpful to keep any ceiling fans or other air circulation devices off in the household for the first few days.

Most clients can return to work and normal daily activities the day after the Lasik procedure is done, and do not require any extra assistance from other friends or family members.  There is usually little to no post-operative discomfort after Lasik has been performed.  It is recommended that patients go to sleep as quickly as possible after the Lasik surgery in order to minimize any post-operative discomfort.  Upon waking, improved vision from the Lasik corrections should already start to be visible.

This improved vision may not be the final product of the Lasik eye surgery.  The improvement to nearsightedness after Lasik is usually quick and dramatic, though there may be some problems in reading easily for the first few days after the Lasik operation.  This is perfectly normal, and should clear up before the week is out.
Patients that use Lasik to improve their farsightedness usually find a dramatic improvement the day after the Lasik surgery.  It might be that there is a temporary blurring of objects in the distance, but this will resolve itself.  If this condition remains for more than a few days, the Lasik physician can recommend and prescribe temporary glasses until vision is stabilized.

These are all typical post-operative recommends for a Lasik patient, in order to feel comfortable with what to expect after the Lasik procedure.  As with any medical treatment, get all of your questions answered by the staff of your Lasik eye center for your individual case.

The procedure for wavefront lasik eye surgery.

The procedure for wavefront lasik eye surgery.

Let's walk through what a client experiences when attending a Lasik center for a Wavefront Lasik procedure.  The procedure itself generally only takes between five and ten minutes for each eye in total, and both eyes are done during the same procedure.  The actual time to reshape the eye with the Lasik excimer laser is usually less than 15 seconds per eye.

Any person's vision problems are generated by small "aberrations" within the eye that prevents the light from focusing objects as they should.  The Lasik equipment locates and classifies these aberrations and then processes them so that the Lasik physician will correct these and allow the light to focus properly once the eye has healed.

In a Wavefront Lasik procedure, the patient stares at one point while a light is sent into the eye, which is reflected back and read by a Lasik Wavefront sensor.  The distortions in this reflected light are mapped using a small computer within the Lasik system, and then this information is used to guide the laser that treats the eye.
Once the light creates the map for the eye, the Lasik surgeon has to create a small flap to access the cornea.  This is done using a laser (this type of Lasik procedure is known as IntraLasik, or bladeless Lasik) or a small blade known as a microkeratome.

This flap is then opened to allow the cornea to be reshaped by the Lasik system.The excimer laser actually reshapes the cornea, which is the crucial part of the Lasik procedure.  In order to determine exactly how to reshape it, the map created earlier by the Wavefront sensor is used to direct the beam of light accurately.  The Lasik physician uses these precise tools to get the clearest vision results possible.

This custom Lasik procedure can not only correct such standard problems as nearsightedness, but can also address aberrations that create light halos, glare, haze, or starburst patterns.  Once the Lasik physician determines that all relevant aberrations have been eliminated, he replaces the flap in its proper position, where it adheres normally and will heal naturally.

As mentioned earlier, this entire Lasik process takes between ten and fifteen minutes per eye.  A patient gets a mild sedative and eye numbing drops to make the procedure both relaxing and painless.  Most people notice an improvement in vision due to Lasik almost immediately.

Once the Lasik procedure is finished, you will get some eye drop medication to lubricate and protect your eyes.  This medication (and the liquid in the drops themselves) may cause some blurring, and so for this reason (and to avoid any eyestrain) you should arrange for someone else to drive you home.  It is also a good idea to go to sleep as soon as possible after the Lasik operation in order to promote even faster healing.

To promote optimal healing the Lasik physician often gives a plastic shield to wear over your eyes for the first night or two.  Follow closely any recommendations by the Lasik physician. Do further investigation into this great new Lasik procedure, and get a clearer focus on your future!

The Facts About Intra Lasik Eye Surgery

The Facts About Intra Lasik Eye Surgery

Now that Lasik vision correction surgery has been accepted for a number of years, there are several popular options for the procedure.  One of these is IntraLasik, or Intralase, or bladeless Lasik.  As the name implies, there is no cutting of the eye with a blade, instead the flap in the eye is made using a laser.  Since bladeless Lasik is a newer procedure, there are a number of opinions around about how well this procedure works.  Let's look at several of these and determine which of these are true or false.

First, more Lasik clients get 20/20 vision or better using IntraLasik.  Any Lasik procedure cannot guarantee perfect vision for every client, though more than 90% get results to at least 20/40 vision.  However, it is true that the new techniques of IntraLasik do get even better statistics for giving clients clear vision.

Some are concerned that the laser that makes the corneal flap is standard, and cannot be tailored to each individual eye like can be done by the Lasik surgeon when using a blade.  This is not true.  The Lasik physician has control over the use of the laser for each individual in the same way that he can control the microkeratome blade.

IntraLasik can be used for both a standard and a custom Lasik procedure.  This is true.  Custom Lasik procedures using Wavefront technology (another somewhat recent advance in Lasik vision correction) can easily be used with a laser making the initial flap.  This custom Lasik procedure, though more costly, is of great benefit for people with unusual eye shapes or problems.

Some have heard that using the laser is less accurate than the standard Lasik procedure.  This is not true, since lasers can be controlled to micron level accuracy.  This gives the Lasik physician extreme control to create exactly the flap needed for this particular individual eye: the precise size, shape, and depth for successful completion of the Lasik procedure.  

Another common fallacy is that IntraLase has not been around long enough for trusted Lasik physicians to have confidence in it.  On the contrary, many of the most honored Lasik physicians strongly endorse IntraLase due to the track record of very good results from the Lasik procedures.  In addition, the quality of the machines and the precision that they give these Lasik physicians is very impressive.  Many of the top flight Lasik doctors recommend this as a procedure of choice, assuming cost is not a significant variable in the decision of which Lasik procedure to use.

Similar to the objection above, some people think that Intralase is not a sufficiently test Lasik procedure option.  On the contrary, more than one million of these procedures have been performed, and the impressive track record for this Lasik procedure has been discussed above.  More and more Lasik physicians are trained in this option, and we will see many more such Lasik procedures in the future.

We hope that this discussion of bladeless Lasik has given more accurate information to those considering this Lasik technique.  Please discuss this option with the professionals at your local Lasik center.

What is the Initial Lasik Eye Exam Like?

What is the Initial Lasik Eye Exam Like?

The first significant step before the Lasik surgery is to have a comprehensive eye examination, in order to be sure that you are a good candidate for the Lasik procedure.  A map of your eye will be created during this exam.  This map is used in order for the Lasik physician to determine how to reshape your eye to give you the clearest post-operative vision possible.

This eye exam will do several things.  Your eyes will be dilated in order to see if there are any irregularities within the eye itself.  The thickness of the cornea will be measured, and a precise map of the cornea will be generated.  The "refractive error" (or the reason why your vision isn't currently perfect) will be accurately analyzed in order for the Lasik procedure to get the best results possible.  Finally, how your eyes generate tears will be closely looked at, as good tear production is essential for the health of every eye.

Before or after these measurements, the Lasik physician will discuss your past medical history to see any previous operations or any ongoing health problems.  A few chronic conditions may make the Lasik procedure not a good option for some people, and also women currently expecting should wait for some time after delivery.  The physician also will discuss the expectations the Lasik client has about the operation and subsequent changes in their lifestyle.

Though most people pass through this Lasik eye exam with flying colors, be prepared for some suggestions or serious discussion.  Your eye map may indicate that a newer form of Lasik procedure might be better, such as one that generates a three dimensional waveform for each eye.  Tear production issues may indicate that the Lasik procedure is not the best option for you, and the Lasik physician may recommend another solution.

If all goes well and the Lasik procedure is scheduled, the physician will review the treatment plan and what the client should do to prepare for the Lasik surgery.  This plan may vary slightly between patients, but in general will look something like the schedule below.  Always follow the recommendations of your Lasik physician closely.
First, contact lenses should be avoided for several weeks prior to Lasik vision correction, since contacts can slightly affect the shape of your cornea.  It is important to let your eyes rest in order to get the most accurate Lasik vision improvement possible.  Hard contacts should be avoided for a month, soft contacts for at least two weeks.

Stop using any lotions, makeup, or anything else that could possibly get into the eye the day or two before surgery.  It is important to have your eyes as rested as possible before the Lasik operation.  Also, arrange for someone else to drive you home after the Lasik procedure itself.

These are the most common steps to prepare you for an easy and successful Lasik procedure.  Make sure you give the doctor all information needed for your case, and follow his directions closely.  The Lasik eye surgery will give you a new outlook in life!

The Lasik eye surgery pioneer!

The Lasik eye surgery pioneer!

One of the first publicized physicians that perform the Lasik eye corrective operation was Dr. Boothe, of Dallas Texas.  He has performed the Lasik operation for a number of different clients, including members of the NFL Dallas Cowboys football team.  There are countless testimonials of how satisfied his Lasik clients were with the surgery, even a number of years later.

One of the important considerations for any doctor is kindness, and Dr Boothe's Lasik patients comment on this trait after their procedures.  They all agree that Dr.  Boothe made them feel very relaxed about the procedure, and took time to answer any and all questions that they might have.  This is especially important with the Lasik process, as eye health is crucially important, and confidence in the doctor makes considering the Lasik option much more feasible.

Dr. Boothe became a specialist of the eye, and especially the cornea, in 1987.

He has performed more than 80,000 Lasik laser vision corrections in that time.  He has also contributed to the field of expanding Lasik practice, with the new VISX three dimensional wavefront procedures.  These procedures are especially useful for those people with unusual configurations of their eyes.

One of the other newer Lasik procedures uses only the laser, instead of the usual Lasik operation using both scalpel and laser.  He is the leader in the performance of this field, and has done more than 45,000 of these operations.  This type of Lasik procedure holds new promise for the field, and should be investigated by anyone considering any type of Lasik procedure.

Looking at some of Dr. Boothe's background will help prospective Lasik clients to look for a physician of similar quality in their area.  Dr.  Boothe's center itself is located in the Dallas metropolitan area, but there are many fine doctors that practice Lasik procedures in all parts of the country.  He has taught a number of other laser eye surgeons in the technique, and so one question that should be asked is where the physician received his training in the Lasik procedure, and which doctors taught the technique.

A most critical part of traditional Lasik surgery is using the microkeratome to make and lift a flap in the eye.  Dr. Boothe's love of medicine and absorption in furthering the techniques used in Lasik make him a pioneer in the field of ophthalmology.  He is board certified by the American Board of Ophthalmology, and emphasizes that any patient should check the board certification for any physician they are considering for performing the Lasik procedure in addition to standard medical certifications, such as the American Medical Association.

One reason that Dr. Boothe entered the field of Lasik surgery was because a good eye surgeon can dramatically improve the quality of life for his patients, as is attested by his many thousands of satisfied patients.  The doctor that a patient selects for the Lasik procedure should have high standards for safety, accuracy, and precision.  This should be reflected in the results and opinions of the patients that the doctor has.  Lasik can be a life improving procedure, and careful selection of a physician in the same mold as Dr. Boothe can make it much more certain.

What is Wavefront Lasik Eye Surgery ?

What is Wavefront Lasik Eye Surgery ?

The wonderful results of Lasik surgery have been improved by research adding new methods, such as Wavefront technology.  This technology gives a Lasik physician the ability to see and accurately map even slight variations in the surface of the eye.  This gives the physician the ability to more accurately tailor a Lasik operation to the individual, and result in even clearer vision.

The concept behind Wavefront technology was originally developed by astronomers, in order to indicate if a mirror or a lens had slight imperfections in it.  It is very important in astronomy to get near perfect optics in order to clearly see the small light sources million of miles away in the universe.  In the 1970s a sensor was created to electronically check these surfaces, and a type of this sensor is now used in the Wavefront guided Lasik procedures.

The idea to apply this technique, or to use this sensor, to the field of ophthalmology and later to the specific area of Lasik vision correction, was begun in Germany.  The physician Josef Bille began using the sensor in his practice, and this started others to refine the sensor and how it is used and to apply it to Lasik technology.  In 1997 the improved sensor, with greater accuracy and speed, was announced to the Lasik laser manufacturers.  This allowed the companies that manufacture the Lasik equipment to develop tools using the Wavefront concept for each of their own laser systems.

The FDA approved the first Wavefront guided Lasik vision correction system for general use.  Initially, the Wavefront sensor makes a map of the eye's imperfections, and this map is sent to the laser that is used in the Lasik vision correction portion of the operation.  This allows for precise eye alteration in order for Lasik to present the best vision correction possible.

The Wavefront technology used in Lasik can be described easily at an informal level.  A small, flat sheet of light (called a wavefront) is passed through the eye, reflected off of the retina, and passed back through the eye and is captured by the Wavefront machine.  If the eye were perfect, the light would return as a flat sheet and be captured that way by the Lasik machine.  However, any imperfections changes the way that the light returns, and this is detected by the Wavefront part of the Lasik process.

A number of these small, flat sheets of light are sent into each eye from various directions and the results returned generated a three dimensional map of the eye to be used in the Lasik vision correction process.  In addition to the commonly known problems of nearsightedness, farsightedness, and astigmatism, there are more than 60 other patterns that are known and can possibly be corrected for.

All of this information generated by the Lasik sensor is converted by software into a set of directions to be carried out by the Lasik excimer laser.  Ask your doctor about this exciting advance in Lasik vision correction, and see if this procedure is right for you!

Eye care after lasik surgery

Eye care after lasik surgery

A person that is considering a Lasik procedure to improve their vision has two major responsibilities: selecting the best surgeon possible for their budget, and understanding and keeping up with eye care after the Lasik operation is done.  Most Lasik procedures go very smoothly, and more than 90% of the patients are happy with their improved vision and have no permanent side effects.  Part of this success is due to good care at home once the Lasik procedure is complete.

The first step in having the best care after a Lasik procedure is to understand exactly what is directed by the Lasik physician.  The prospective Lasik patient should be given a good understanding of the entire process when they first visit a Lasik center to interview the physician and the staff.  On the day of the procedure, a member of the staff should very carefully go over exactly what steps should be done to encourage optimal eye health and healing after the Lasik operation.

One thing that the patient should ask is what side effects are to be expected directly after the Lasik procedure, how long they should last, and which symptoms should be promptly told to the Lasik physician or member of the staff.  A number of symptoms, such as fluctuating vision or halos around lights, are to be expected and are not a cause of worry.  Ask the staff about any postoperative symptoms that are unclear, to make sure that they are thoroughly understood.

Each Lasik physician has their own recommended procedures for their patients, but here is a list of typical suggestions that most Lasik centers recommend.  First, get some sleep as soon as possible after the Lasik procedure is done.  This gives a great boost to the healing process.  Second, avoid any contact, bumping, or rubbing of the eyes for at least five days after the Lasik procedure.  Most Lasik eye surgery centers have some kind of eye guards to wear at night to prevent patients from rubbing their eyes in their sleep.  

Third, try to avoid eyestrain for some days after the Lasik procedure.  It is tempting to try to read all of the signs and words that were previously blurry, but avoid this temptation at least for the large part.  If any light sensitivity or glare is noticed, wear dark sunglasses for several days until this problem resolves itself.  Some common Lasik side effects are temporary halos around lights, especially when viewed at night, but this is not a problem to be concerned with.

It is very important to keep the eyes well lubricated in the days following a Lasik operation.  Every Lasik physician will give eye drops to help this, and patient should be especially aware of this before going to sleep.  A Lasik procedure may increase eye dryness temporarily, and during sleep this may make the eyelid stick slightly to the eye.  When the patient wakes up, opening the eyelid is equivalent to rubbing the eye.  The physician should be notified if this happens, for there are other varieties of eye drops that will solve this problem.

Taking these simple steps will give nearly all Lasik patients an easy postoperative experience without any problems.

Have no fear of Lasik eye surgery!

Have no fear of Lasik eye surgery!

Thinking about eye surgery using a Lasik procedure is a big step, and many people are a little hesitant to ask the questions that they have.  The Lasik procedure, though widely talked about, is not discussed in detail, and people tend to fear the unknown.  This report addresses some of the more commonly held fears, and talks about the experience for the vast majority of people that undergo a Lasik procedure.

A most common fear when thinking about a Lasik procedure, or really thinking about any surgery in general, is the possibility of pain during or after the operation.  Since the Lasik surgeon works on patients that are conscious, this is a widely held apprehension.  In every operation the Lasik surgeon applies numbing drops into the eyes before the procedure starts, and the patient is also given a mild sedative to relax them and make sure that they are comfortable.   Though a small pressure to the eye may be felt during the Lasik procedure, the process itself is relatively pain free.

The surgeon does use a laser in the eye to help reshape the cornea during the Lasik procedure.  Many folks are worried about the laser being shone directly into the eye, or that they might look away and, due to this, develop a serious complication with their eyes and the Lasik laser beam effects.  In actuality, the laser is only active for ten to fifteen seconds for each eye, and the Lasik machine has a tracking system that allows the beam to be on only when the eye is in the correct position.

Another general fear for people contemplating a medical procedure is fear of "the scalpel".  Any Lasik procedure uses only a very small microkeratome blade to approach the eye, or some more recent Lasik innovations have the laser itself created the flap and avoid using any hard surface at all.  There is no reason to be concerned about a scalpel, for the Lasik physician does not use one.

Many wonder about the horror stories they hear about this or any other operation, and wonder about serious consequences like going blind.  According the government statistics taken by the FDA, there are no reported cases of blindness due to a Lasik operation.  Actually, the risk of a serious permanent complication due to the Lasik procedure is less than 1 percent, and the risk of any permanent complications even if not serious (such as light halos) is 3 percent or less.  It is extremely rare for a patient to not have improved vision after a Lasik procedure.

If the thought of being awake and having your eyes open during the Lasik procedure bothers you, remember that you will be given a mild sedative for the procedure, and that your eyes will have numbing drops administered to them.  If the thought of actually seeing the Lasik physician's hand approaching your eye is bothersome, be comforted that the surgeon applies drops to the eye that blacks out the vision in that eye for ten to fifteen seconds, which is long enough for the procedure to be done for that eye.

This introduction has hopefully addressed the most common fears about the Lasik procedure.  For anyone that might gain a better life quality with improved vision, please visit your local Lasik eye surgery  clinic and discuss the procedure in detail with the professionals there.

Is Lasik Eye Surgery for you?

Is Lasik Eye Surgery for you?

So many people are interested in the Lasik vision correction procedure, and want to know the benefits, the risks, and how the Lasik procedure works.  One of the first things to consider is what requirements a person should meet in order to have a successful Lasik procedure.  Though each individual case should be discussed with a qualified Lasik physician, here are some guidelines to see if you are a good candidate for Lasik vision correction.

First, the eye should be properly matured.  This means that anyone under the age of 18 really needs to wait before a Lasik procedure is done, for it is likely that the shape of their eye will continue to change for several years.  If the eye shape changes after the Lasik operation is done, the clarity of vision will be affected.  Some Lasik physicians recommend waiting until age 25 in some cases.

In addition to an age cutoff, the vision prescription for the Lasik candidate should be stable for at least one year, and preferably for longer than that.  This is for the same reason as above, that the Lasik procedure will only continue to be effective if the eye shape remains constant after surgery.

One comment about age cutoffs should be made with regard to Lasik surgery.  There is no maximum age, as many patients in their fifties to their eighties have had a very successful Lasik procedure.  The main consideration in these cases is enough tear production for successful healing and lubrication after the Lasik vision correction.

The eyes of the Lasik candidate should be healthy.  This means that any person undergoing a Lasik procedure should have had no eye infection or injury for at least a year, and must have no scarring on the cornea of the eye.  In addition, they must not have any recurring eye problem, such as a history of herpes infection in the eyes.

The medical history of a prospective Lasik client also plays an important part.  Some chronic conditions, such as autoimmune disorders like Lupus, will prevent some people from being able to schedule a Lasik procedure.  You should be very clear about any and all medical conditions that are current, or even completed ones in the past.  Also, women who are pregnant or nursing should wait to have a Lasik procedure scheduled.

A good Lasik physician will also not schedule people with dry eye syndrome for Lasik vision correction.  Having sufficient tear production is important, though for minor problems this may be aided by medication during the healing process.  In addition, those people with eyes that dilate very widely are not good candidates for Lasik. 

These are most of the most common reasons that a person should look at some other eye improvement choice other than Lasik.  Most generally healthy people with standard vision problems benefit greatly from a Lasik procedure done by a trained, professional Lasik physician.  Look for a good Lasik eye surgery center in your area and discuss your individual case in detail.

Choosing a good laser eye surgeon

Choosing a good laser eye surgeon

Improving your vision with a Lasik procedure could be one of the greatest gifts you could get for yourself.  However, as my mother used to say, "Your eyes are precious."  It is important to entrust the Lasik operation to a doctor that you trust and have confidence in.

Let's begin with three factors that should NOT be the sole reason you select a doctor for the Lasik procedure.  The location of the office is not particularly important, and a number of people travel long distances to have the Lasik procedure done, for a truly professional doctor will only need to be visited two or three times.  Also, cost or the type of Lasik technology used should not be the sole factor.  The range in surgical skill for a Lasik operation does vary, and there is the old saying "you get what you pay for."  Further, though the newer types of Lasik procedures do have their benefits; many eye doctors in a large metropolitan area often offer two or three Lasik variants.

There are several ways to determine which is the best doctor for you in your area.  One of the qualities to look for in a good Lasik physician is someone who can accurately assess your situation, and advise you if Lasik is even a good choice for you and your lifestyle.  A physician that takes the time to discuss your own physical condition and situation with you is a good indicator that this is a Lasik physician that you can rely on.

Look for a Lasik eye surgeon which has a solid reputation in the area, and has a good track record.  A physician that advertises in a magazine is not a sufficient recommendation to put your trust in that doctor, and needs more investigation before agreeing to have him do your Lasik procedure.  Sometimes a Lasik center with a large advertising campaign and discounted prices may be indicating that the quality of the surgery is not excellent, and this could be a red flag to avoid that center.

A good Lasik doctor should be involved in the entire Lasik process.  As mentioned above, he should take time to assess your particular case and discuss it with you.  Not only should he do the exam, but he should also perform most or all of the preoperative exam, and also should meet with you personally to monitor the success of the procedure at the dates for checkup.  There are stories from some Lasik centers of the patients never seeing the physician again after the operation until they complained strenuously of some particular problem.

Make sure the physician is honest in their assessment of the general Lasik procedure, and his track record in particular.  Ask for individual examples of patients that the physician dissuaded from having the Lasik operation, and why.  Ask how many Lasik procedures the doctor has done in total, and how many in the last two years.  An experienced surgeon should have performed in the neighborhood of 1000 Lasik procedures, with at least 500 of those in the last two years.

Use these questions as a starting point to investigate the Lasik eye centers in your area, and even the highly recommended ones in nearby major metropolitan areas.  It will be time well invested, and the first step to a clearer future.

Eye Care

Eye Care

Regular eye exams are important even for people who are not having eye trouble. These are in-depth routines that are normally performed by either an Ophthalmologist or Optometrist. How often a person needs an eye exam hinges on a number of elements including age, overall health and whether or not eye disorders run in the family.

Kids with no eye trouble need only have their eyes checked out during regular visits to their pediatrician. This evaluation is ordinarily referred as a vision screening and ought happen at a minimum, every 2 years. A vision screening isn't as across-the-board as an eye exam, but it is priceless in noticing early signs of eye/vision trouble.

For grownups without eye trouble, eyes ought be tested once between the ages of 20-29, twice during the next 10 years, 2-4 times during the next 10 years and after age 65, eyes should be examined once every 1-2 years. People wearing corrective lenses should have their eyes tested annually. Those with eye disorders should work out an testing schedule with their eye doctors.

What is involved in  an eye exam

Employing a light source, an external examination ascertains that the eyes 'look' right. You will follow the doctor's pen (or other object) with your eyes to ensure the eye muscles function properly. Whilst you read the illuminated chart with letters that get smaller the further down you go, your doctor is checking out your visual acuity. If you need corrective lenses, you'll get a refractive appraisal, a test that determines how light wave bend. The outcomes of these tests help the doctor decide your prescription. He may put a Phoroptor, a device that resembles a big black mask, over your eyes in order to fine-tune these measurings.

Your peripheral vision will be screened. A slit lamp exam uses a microscope that emits a sharp ray of light to evaluate the cornea, lens and iris. The back of the eye is also analysed and lastly your eyes will be tested for glaucoma.


Differences between the eye care specialists.

Ophthalmologist vs. Optometrist

The duties and skills of an Ophthalmologist and an Optometrist are generally different, all the same just about most people erroneously use these terms interchangeably. Both professions involve eye care nonetheless the primary difference between the two is the presence of a medical degree. It's this degree that denominates an Ophthalmologist as a medical doctor who's been trained in all areas of eye care including the power to diagnose and care for eye disorders and diseases.

Ophthalmologists are qualified to perform eye surgery and they likewise know how to conduct proper eye measurements so they can precisely prescribe corrective lenses. Their training helps them administer advice for preventing blindness and also enables them to attend to those who are blind. In addition to advanced educational training, Ophthalmologists must be trained in clinical and surgical settings.

Optometrists routinely perform eye tests. During such eye examinations, Optometrists will also find out the need for, fit and prescribe corrective eyewear and/or lenses. Optometrists can likewise screen patients for certain eye disorders.

Many patients are very satisfied with the improved quality of life that they experience after LASIK Surgery. Read on to decide whether LASIK Surgery is right for you. 

The different types of LASIK Surgery

There are two basic types of surgery: Standard LASIK and Custom LASIK. With either type, the preparation work and post-operative procedures are similar. The difference between the procedures involves the customization of the laser.

Standard LASIK

Prior to the scheduled procedure date, the eye surgeon meets with patient to re-test for certain eye problems and diseases. When it's confirmed that the patient meets the requirements, a procedure date is set.

On the day of the procedure, the eye doctor may perform another corneal topography to confirm that nothing has changed that would require changing the procedure. Three types of eye drops are then administered. The drops anesthetize the eye, protect the eye from post-operative inflammation and protect the eye from infection.

Next, the patient reclines and the laser is positioned overhead with the eye surgeon above it. To remove the flap, the patient's eye must first be stabilized. The eye is kept from blinking by placing it into a restrainer. Suction is administered to the eyeball and the microkeratome makes one swift slice across the top of the cornea. The resulting flap (which should still be hinged to the eye) is pulled away with tiny tweezers.

The laser then emits a pre-determined number of laser pulses to remove the excess tissue, a process which takes literally seconds. The flap is pulled back into place and saline solution clears the eye of any debris. The eye is covered and the procedure is finished unless the other eye is receiving a LASIK Surgery treatment.

Custom LASIK Surgery

In standard LASIK, the computer inside the laser determines the number and location of laser pulses based solely on the patient's prescription. With custom LASIK, the eye surgeon creates a three-dimensional image of the eye. The image results are then fed into the laser's computer and the patient receives a laser treatment that is truly customized to that eye.

Risks and complications

As with any surgical procedure, there are risks associated with LASIK Surgery. The procedure may under- or over-treat the eye. Under-treatments can be corrected with additional surgery however over treatment generally results in the patient needing to continue wearing corrective lenses. Loss of vision or compromised vision, especially at night, are other risks. Dry eye syndrome can develop. And vision that has been surgically corrected may decline over time. Another serious risk involves using an inexperienced ophthalmologist.

Tips on selecting a LASIK Surgery surgeon

Get referrals from people you trust and then make arrangements to interview several candidates.

Make the most of the pre-procedure consultation. Prepare a list of questions to ask each surgeon and record the answers. It's important to understand what care the ophthalmologist intends to provide during all stages of surgery: before, during and afterwards as well as all costs.

Remember that low cost doesn't mean top quality. Your eyesight is far too valuable to allow cost to be the determining factor.

Information on Corrective Eye Surgery

Information on Corrective Eye Surgery

Several types of correct eye surgery exist today and these different types of corrective eye surgery fall under two main categories: Excimer Laser procedures and Non-Excimer laser procedures. As is the case with other conditions that affect the body, major technological advances have been made in recent years in the field of corrective eye surgery. The following is a brief introduction to the two categories.

Excimer Laser Procedures

An Excimer laser is a tool that was approved for the treatment of nearsightedness ranging in severity from mild to moderate. Use of the Excimer laser is complicated and it's important to work with ophthalmologists who are both trained in the surgical procedure and who have demonstrated the ability to properly operate and calibrate this precision instrument.

The Excimer Laser was originally approved for PKR, or Photorefractive Keratectomy and its usage was later expanded for LASIK procedures, or Laser in situ Keratomileusis. With PKR, the cornea is reshaped by eliminating excess tissue from the cornea's outer surface. With each computer calculated lightening-fast laser pulse, a microscopic ultraviolet light beam removes the excess tissue. After only a few minutes and the application of local anesthesia, the procedure is over. In just a day or so, patients can resume normal activity.

In a LASIK procedure, the eye doctor rather than the laser's built-in computer determines where incisions will be made and how much tissue will be removed. This is a more complex and invasive procedure and it is one that is recommended for more severe refractive conditions. Using a microkeratome (a knife), the eye surgeon slices and then pulls back a flap of the tissue covering the cornea. With the tissue out of the way, the laser is then used to remove tissue and reshape the cornea. The flap is put back into place and the patient typically can see well enough to drive home after the procedure. LASEK and epi-LASIK are variations of the LASIK procedure.

Non Excimer Laser Procedures

These are procedures that rely on artificial implants, surgery and reshaping to correct eye problems. Lens implants are effective for individuals who have cataracts, nearsightedness and farsightedness. Intraocular lenses or IOLs are used as replacements for the damaged cloudy lenses caused by cataracts. New and improved artificial lenses now incorporate the use of hinges that allow the eye to move and act like a real lens.

Other types of implantable contact lens can correct nearsightedness and farsightedness. They act much like removable contact lenses but require no maintenance and wearers cannot feel these lenses and implants.

Thermokeratoplasty involves the use of heat to manipulate the collagen within the cornea. In doing so, refractive errors can be corrected in a matter of minutes. There are two types of Thermokeratoplasty procedures. Laser thermal keratoplasty or LTK involves the use of holmium YAG laser and CK or conductive keratoplasty involves use of radiofrequency waves.

Astigmatic Keratotomy (AK) involves cutting the cornea in order to reshape it. However, its use has diminished since laser treatments involve less risk and are far more effective at reshaping the cornea.

Information on LASEK Laser Eye Surgery

Information on LASEK Laser Eye Surgery

LASEK (Laser Epithelial Keratomileusis) laser eye surgery takes the most beneficial elements of two other types of laser eye surgery and combines them into one very effective surgical procedure. These other two laser eye surgeries are LASIK and PRK.

Unlike the LASIK procedure which involves using a sharp blade to slice off the top of the cornea, LASEK uses a solution consisting of diluted alcohol to loosen a thin layer from the epithelium so that it can be moved off to the side.

Benefits of LASEK laser eye surgery

One benefit of LASEK laser eye surgery is that it eliminates the risks associated with the corneal flap. With LASIK surgery, a very sharp blade called a microkeratome is used to cut the corneal flap. There have been cases in which the flap was cut too deeply or cut off completely instead of leaving it attached with a hinge, both of which are capable of causing any number of serious vision problems.

Healing is faster with LASEK because there is no cutting and because the epithelial flap can be used somewhat as a natural bandage after the procedure is finished. And unlike PRK, the chances of developing a glare after the operation are greatly diminished when using LASEK.

Risks/disadvantages

Risks associated with LASEK laser eye surgery are greatly diminished mainly due to the fact that no sharp device is being used to cut the cornea. There is some pain but it is minimal and is most often treated with over the counter medicines. Also, it is not possible to guarantee any type of vision results and glare, halos and dry eyes are potential side effects.

The LASEK procedure

Prior to the LASEK procedure, a patient must provide the eye surgeon with a complete medical history. Eye tests and other diagnostic procedures are undertaken to ensure the patient is a good candidate for LASEK laser eye surgery. On the day of the procedure, the eye is cleaned and prepped and an eye drop to numb the eye is administered. A special tool will hold the eyelids in place, preventing them from blinking.

The diluted alcohol solution is applied, the epithelium loosens, and it is gently pushed out of the way. The pre-calculated beams of ultra violet light are then pulsed onto the cornea and in just a minute or so, the procedure is complete.

Most patients will have blurred vision at first and won't be able to drive home from the procedure. Most need a day or two to rest. Vision will vary over the ensuing months.

For best results, always use an eye surgeon who has experience with the LASEK laser eye surgery procedure. Never be afraid to ask a surgeon you're considering for the names and contact information of previous patients. If you get a list of contacts, be sure to call and ask about their experiences.

About Epi-LASIK Laser Eye Surgery

About Epi-LASIK Laser Eye Surgery

The most advanced of the surgical eye procedures using laser technology, Epi-LASIK laser eye surgery combines the best of traditional LASIK surgery with the best of the LASEK and PRK laser procedures. Epi stands for Epithelial and LASIK stands for Laser in situ Keratomileusis. Basically this newest procedure involves gently separating the epithelial from the top of the cornea using an epikeratome rather than slicing the top of the cornea and creating a hinge as is the case with LASIK.

A good candidate for Epi-LASIK laser eye surgery is someone who has a very thin cornea and who also has mild to moderate farsightedness, nearsightedness or astigmatism. As with the other types of laser eye surgery, best vision is achieved by using laser beams to reshape the cornea.

Benefits of Epi-LASIK laser eye surgery

The two main benefits of the Epi-LASIK procedure are its quicker recovery time and the speed at which vision is restored. Because the cornea is not cut with a microkeratome (a sharp blade) the cornea does not have to heal. And because only a thin layer of the epithelial is separated, it too has the ability to heal quickly. This type of procedure eliminates the potential risks associated with incorrectly cutting the cornea, which in some cases can cause a number of vision problems including a permanent loss of vision. There also is less pain.

Risks of Epi-LASIK

While no surgical procedure is without risk, proper candidate screening including thorough diagnostic testing will significantly reduce the risks associated with Epi-LASIK surgery.

The Epi-LASIK procedure

As with the other laser eye procedures, the Epi-LASIK procedure also takes less than 10 minutes to complete. Anesthetic drops are placed into the eye to minimize pain and discomfort. From there, the epithelial must be moved off to the side so that the laser can reach the intended target area.

Specialized equipment is used to first stabilize the eye. Then, the epithelium separator makes a pass across the eye and flattens the cornea which makes it easier to separate the epithelial. It is not separated completely, rather it remains attached in the middle instead of at one side as happens with the LASIK procedure. A small spatula-type tool is used to move the flap out of the way.

The laser then begins emitting pulses of ultraviolet light, quickly removing the excess tissue from the cornea. As the laser pulses, the cornea is being reshaped. This continues until the proper amount of excess tissue is removed, as determined by the eye surgeon. When finished, antibiotic drops are placed in the eye to protect against infection, and a contact lens-like bandage is applied. Those opting for the Epi-LASIK eye surgery can usually resume normal activity the day after the procedure. Several follow-up visits are required to monitor healing and vision.

It's important to choose an Epi-LASIK eye surgeon with care. Discuss the surgeon's experience with this type of procedure including success rates. Also discuss the type of care that will be provided during all stages: before, during and after the procedure and associated costs.

Lasik eye surgery

Lasik eye surgery

Advertisements for LASIK surgery are everywhere. Anyone who wears contact lenses and eye glasses can relate well to the feeling of finally being free of the maintenance and bother involved in wearing either. As tempting as the advertisements are, LASIK Surgery may not be right for everyone.

Understanding LASIK Surgery

LASIK is the acronym for laser in-situ keratomy, eye surgery involving use of a powerful laser called an Excimer. The Excimer has been designed especially for working in the delicate eye area. The laser works quickly to reshape a person's cornea, which generally is all that is needed to correct myopia (known also as nearsightedness), hyperopia (farsightedness) and astigmatisms.

Reshaping the cornea generally is a simple matter of removing excess tissue from beneath the cornea. In order to get at this tissue, a tiny flap must be pulled back from the cornea's surface. The laser can create this flap, and so can a tool called a microkeratome blade.

Laser pulses zap as much excess tissue as the ophthalmologist determines after reviewing a very detailed image of the cornea called a corneal topography. In literally a matter of minutes and often without feeling any pain, the shape of the cornea is corrected and vision restored. In fact, vision is usually restored so quickly that a patient can drive him or herself home from the procedure.

Deciding on LASIK Surgery

One of the biggest decisions a person interested in LASIK Surgery needs to make is whether this type of eye surgery is affordable. It is categorized as a cosmetic type of surgery and therefore many health insurance plans won't provide coverage.

The costs for this surgery vary considerably, but generally the costs of using a reliable and knowledgeable ophthalmologist will run several thousand dollars – per eye! So cost is definitely one big consideration.

If it's decided that the costs are justifiable, there are some individuals for whom this type of surgery may not be effective. Only healthy eyes and eyes that have stopped changing can be operated on. There also are certain prescription limitations which automatically disqualify a patient from this type of surgery.

A comprehensive review of a prospective patient's medical history is undertaken prior to LASIK Surgery. A number of tests are also performed at an initial consultation for the purpose of detecting eye problems and/or diseases which could affect the surgery. Due to hormonal considerations, LASIK Surgery cannot take place when a woman is pregnant or when either a man or a woman has a compromised immune system as this condition could jeopardize the eye's recovery.

To summarize, if such a procedure is affordable and the eyes meet the procedure requirements, LASIK Surgery may be a good option to pursue. The surgery itself has a very high success rate and combined with the fact that it's practically painless, it probably makes sense to give it a try.

The next section will review the different types of LASIK eye Surgery that are available and the risks and possible complications of each.  

Contact lenses and children

Contacts lenses and children

There's no age restriction on contact lenses for kids. In fact, even very young children can wear them and many do for a variety of reasons. How can one decide whether contact lenses for kids make sense? Like any decision, it's important to consider the benefits against the disadvantages.

Contact lenses for kids make sense for the same reasons they do for adults. They help enhance appearance, they are comfortable to wear and they are a good choice for improving vision. Add to these reasons the facts that fitting a child isn't an issue and that children have all the same options as adults including daily wear, extended wear, continuous wear and disposable and it's difficult to argue against contact lenses for kids.

Kids who participate in sports find that wearing contact lenses is much easier than dealing with the hassle involved in wearing eyeglasses. Eyeglasses and sports aren't always a good match. They break more frequently and replacing children's eyeglasses isn't cheap!

Kids can be cruel, and children who wear eyeglasses find that they're frequently subjected to unnecessary taunting and name-calling. Such behavior can seriously impact a child's self-esteem and confidence, especially when they're young and don't know how to disregard the words being said.

Studies have shown that contact lenses for kids, in particular rigid gas permeable styles, have the added benefit of helping to keep nearsightedness from progressing. 

There is something else to consider before making a final decision, however. Although a child's age isn't necessarily a consideration, a parent may wish to consider a child's maturity level. With the decision to wear contact lenses comes an understanding that the wearer has certain responsibilities that must be upheld. Since no two children mature at the same pace, a parent really is the only person who can make this determination.

It helps to think about the ways in which the child does or does not currently show responsibility. For example, how is the child at caring for pets, or at finishing chores or at completing school assignments?

If a child isn't yet mature enough to handle the responsibility, the parent then has to determine whether he or she is willing to take responsibility for cleaning, maintenance, insertion and removal of the contact lenses and also for scheduling eye examinations and follow-up visits as necessary.

If a child is mature and is motivated, that child likely will be a good candidate. And since most children take instruction well, especially when someone other than a parent gives it, they generally are very good at wearing and caring for contact lenses as they've been instructed by the eye doctor.

Contact lenses for kids do present the same risks as adults have including a higher incidence of eye infection, dryness or abrasion. Some children, even though they may be very motivated, are not good candidates for wearing contact lenses either.

As always when in doubt, talk the decision over with someone who has experience prescribing contact lenses for kids.

Colored Contact Lenses

Colored Contact Lenses

Changing your eye color to match your mood or your outfit with colored contact lenses has never been easier! They are a great fashion accessory and even if you don't need them for vision corr, that doesn't matter. You can still get colored contact lenses in an assortment of vibrant colors.

Right now it's estimated that only a small percentage of contact lens wearers realize they're good candidates for colored contact lenses. Most don't realize that there's been an explosion of availability and that now almost every contact lens prescription is available in practically every standard color option. And even when people do realize this, many are hesitant to give colored contact lenses a try. But don't worry. The color change can be subtle or it can be dramatic and that's part of the fun of wearing them.

Even though you may not need them to correct your vision, if you want colored contact lenses you will have to visit an eye doctor to obtain a prescription. A prescription for contacts that doesn't include vision correction is called a plano prescription. This type of prescription measures the width and the curvature of the eye and will insure that the contact lenses fit properly. If they don't fit right you'll know in a moment because the pain will be persistent and irritating.

Unfortunately, there's a belief among wearers of colored contact lenses that because a pair lacks vision correction it's okay to share the contact lenses with others. This is wrong! Under no circumstances is it ever a good idea to share contact lenses so don't. Not only might they be the wrong size and cause discomfort, if they haven't been cleaned, the other person likely will introduce harmful bacteria into the eyes which can cause irritation and other eye problems.

Within the world of colored contact lenses you'll find many options and it's important to understand what these options are. For example, opaque colored lenses are absolutely necessary when a person wants to completely change eye color. Colored lenses are actually tinted, and besides changing color you'll find other types of tints, some of which aren't necessarily designed to change eye color.

One of the benefits of a visibility tint is that the tint makes the lenses easier to handle by making them easier to see. Clear contacts can end up anywhere when they're dropped and they'll be invisible and nearly impossible to find. But the colored tint on the lens will help pinpoint their location. Enhancement tints have a deeper tint that will enhance and intensify a person's eye color.

Lenses that are coated with UV/UB protection tints are preferred among those who participate in outdoor sports. The tints help to reduce glare which improves vision and hopefully the game. And speaking of sun protection, there is a brand of colored contact lenses that darken to a color that resembles that of sunglass lenses when exposed to light. Once inside, the color transitions back into clear.

Would you be able to match your glasses to your personality?

Match your eye glasses to your personality

In this competitive world of ours, image is everything. And even if you don't think of yourself as being 'image-oriented' deeper insight into your personality might lead to startling revelations. Either way, when it comes to choosing eyeglasses, it'll be worth your time to look for a style that fits your personality.

That's not to say that if you're feeling blue, you should opt for blue-colored frames or lenses. What it means is that before you head over to the 'discounted frame' section, you need to stop and think about who you are and how you live.

Are you older, younger or somewhere in between? Do you consider yourself to be trendy or conservative? Do you have a career or are you a student? What is your career or your area of study? Are you driven by name brands or do names not impress you? Do you look at eyeglasses as a fashion accessory or a necessary evil?

If you've answered these questions, you might wonder, 'Now what? So what if I'm days away from becoming a Baby Boomer and I work a desk job? How is this going to help me choose an eyeglass style?'

Well, one solution is to discuss these self-analysis results with your optician so that together you can work towards finding a suitable pair. A good optician will know which styles are 'in' and which are finally on their way 'out'. He or she may also be familiar with matching eyeglass shapes, styles and coloring to face shapes, much in the same way as a hairdresser can usually recommend a flattering hairstyle.

Plus an experienced optician will know the inventory well. He or she will know how long a particular pair will take to order, about the materials used in each of the various manufacturing processes and whether they're durable or delicate, about the total costs involved from start to finish for the various styles, and other types of useful information that you may not have thought about.

But if you're still confused as to which eyeglass style will best match your personality, here are a few more tips.

If you run in conservative circles, stick with conservative styles and colors. Neutral colors including brown, gray and silver and standard lens shapes such as rectangles and ovals are good choices.

If you prefer to be the center of attention, then choose eye glass styles that will get noticed. Look for unusual shapes and bold colors. If the price is right, get several pairs so you can mix and match with your wardrobe and other accessories.

If you like trends but want a style that has staying power, look at the newest materials being used for eyeglasses such as titanium, stainless steel and memory-metal.

Students and those with a creative or artistic flair look best in styles that help express their individuality. There are no rules here except to steer clear of 'traditional' styles.

Choose specialty styles if you need eyeglasses for a specific purpose such as working at a computer, eye protection, sports and hobbies or driving.

Information on Cataracts and Cataract Surgery.

Eye Care– Cataracts and Cataract Surgery

More than 60 million individuals around the world have cataracts. Cataracts are the #1 cause of blindness but fortunately, cataracts are highly treatable with cataract surgery.

What is Cataract?

Over time the eye's lens, which is transparent in a healthy eye, starts to become cloudy or opaque. As individuals age, protein levels in the eye begin to decrease which is why there is no way to effectively prevent cataract from developing. Other factors can cause cataract such as head injury and certain diseases, but their appearance is primarily due to age.

There are 3 different types of cataracts and each type affects a different part of the eye. At the center of the lens is the nucleus and the most common of the cataracts affects this region. Cortical cataract and subcapsular cataract are more common in individuals who have diabetes.

Symptoms of Cataract

Vision that is cloudy or blurred is the most obvious symptom of a cataract. Nearsightedness can increase and images that were once clear can appear distorted when cataract is present. Less noticeable symptoms include the need for more and brighter light when reading, sensitivity to light, trouble seeing at night, double vision and colors that fade or seem 'yellow'. These symptoms develop because the cloudiness on the lens prevents it from refracting light properly.

Who is at risk?

Everyone is at risk of developing cataract and the likelihood that this type of eye problem will develop increases with each passing year. Simply stated, anyone fortunate to reach old age will likely develop cataract.

Risks increase if there is a family history of cataract. Steroids and some medications can also increase the chances of developing cataract as can eye injury or previous eye surgery. Those with diabetes also have an increased risk.

Early detection/treatment

A routine eye examination is the most effective way of detecting the presence or development of cataract. Because blurred vision can be caused by a number of factors, proper diagnosis is important.

It used to be that a person with cataract in one or both eyes would have to endure painful surgery to remedy the situation. But today, cataract surgery is an outpatient procedure that involves replacing the cloudy lens with an intraocular lens (IOL). The success rate of cataract surgery is extremely high. And surgery is the only option.

Cataract surgery is not recommended until the loss of vision becomes troublesome and impacts quality of life. Cataract generally develops gradually so in many cases, vision in the early stages can be corrected with prescription eyeglasses. An ophthalmologist can determine the stage at which cataract surgery is necessary.

It's important to note that some people with cataract also have other types of eye problems. For them, cataract surgery may not restore vision. Again, an ophthalmologist can help with this determination.

When cataract surgery is performed, an amazing 95% of the surgeries involve no complications whatsoever. Local anesthesia, tiny instruments and a microscope are generally all that is needed to perform successful cataract surgery.

What causes Blepharitis?

Eye Problems – Blepharitis

What is Blepharitis?

When the eyelids can become inflamed, the problem in most cases is a chronic eye disease called Blepharitis. Similar in nature to the skin condition called eczema, in case of Blepharitis, the eyelids become red, scaly and irritated.

There are two basic types of Blepharitis: Seborrheic Blepharitis and Staph Blepharitis. The most notable symptom of either type is inflammation on and around the eyelids that can be accompanied by irritation and painful itching. In some cases, tiny ulcers develop along the eyelid margins which are the areas that touch one another once the eyelid closes.

Symptoms of Seborrheic Blepharitis

Individuals suffering from Seborrheic Blepharitis generally also suffer from skin conditions that affect other parts of the body including the scalp, chest and back.

With Seborrheic Blepharitis, there is a problem with the tear film that the body produces to help protect and lubricate the eyes. It can be either a problem with the quality or the quantity but regardless, the resulting tear film causes greasy scales to form at the base of the eyelashes. These scales flake off easily and cause irritation. When insufficient quantities of tear film are produced, usually because the glands are blocked, the eye does not get lubricated properly. The dry spots cause the eyes to feel gritty.

Symptoms of Staph Blepharitis

Staph Blepharitis is actually a childhood eye disease that is caused by a bacterial infection. This condition generally does not go away. Its symptoms include the development and accumulation of crusty material at the base of the eyelashes. The crust often affects a person's ability to open their eyes after sleep. Sometimes, after the crusty matter is removed, tiny ulcers remain that begin to bleed or otherwise ooze. Sties can develop, as can red eye, and the eyelashes can become weak and break. If the infection is not treated properly, over time, the cornea can become scarred.

Who is at risk?

Both adults and children can develop Blepharitis however it is more prevalent in adults. There is an increased risk in children diagnosed with Down's syndrome.  

Early detection/treatment of this eye problem

As with other diseases of the eye, Blepharitis is typically diagnosed during a routine eye exam. Since one cause of this condition is poor hygiene, the most effective treatment for Blepharitis involves keeping the eyelid margin area super clean. To prevent irritation from excessive cleaning, it is often recommended that this area be cleaned with a shampoo that is formulated for babies. A washcloth can also be used to help remove the scaly deposits.

A hot pack or warm compress applied to the affected areas is effective at reducing pain and swelling. When ulcers are present, a hot pack can also help speed the healing process.

When the condition is caused by dry eyes, lubricants are effective treatments. If necessary, antibiotic ointments and creams can be applied to affected areas. Some people are prescribed steroids to help reduce the inflammation however their use should only be a short-term treatment option.  

How conjunctivitis affects your eyes.

Eye Care – Conjunctivitis

What is Conjunctivitis?

Conjunctivitis is an eye problem in which the conjunctiva, which is the mucous membrane that covers the eyelid and the white part of both eyes, becomes inflamed. There are two main types of Conjunctivitis, or pink eye as it is more commonly referred to. The first results from a bacterial or viral infection and the other results from an allergic reaction.

The infective form of Conjunctivitis, if it's caused by bacteria, is highly contagious with the hands being the primary vehicle for transmission. Conjunctivitis that results from an allergic reaction is typically a seasonal condition as are most allergies.

Conjunctivitis can also result when a person is sensitive to certain facial products and cosmetics. This latter form is sometimes referred to as irritant Conjunctivitis. Allergic and irritant Conjunctivitis are not contagious.

Symptoms of Conjunctivitis

The symptoms of the infective form of Conjunctivitis include discharge that is watery or sticky, eyes that water and feel gritty, and eyes that feel as if they have been glued together upon waking. Mild soreness is sometimes a symptom. The part of the eye that is normally white will also become red or pink, which is why Conjunctivitis has earned the nickname 'pink eye'. Because Conjunctivitis often develops along with a common cold, a person may also have symptoms of a cold including runny nose, mild fever and a sore throat.

With the allergic form of Conjunctivitis, eyes are itchy and the eyelids may appear puffy. There may also be a discharge from the eyes that appears white or watery or ropy.

Who is at risk?

Anyone is at risk of getting Conjunctivitis. Because it can be contagious, a person with Conjunctivitis needs to take measures not to spread it. It's difficult because it is normal to rub the infected eye as a way of providing temporary relief. However, if hands are not washed afterwards and the cause is bacterial, the bacteria can be transferred to another individual by coming into contact with the infected hands.

People who have a history of allergies, particularly hay fever, are at increased risk of developing the allergic form of conjunctivitis.

Early detection/treatment

Infective Conjunctivitis with its notable pink eye often will accompany a common cold making this eye problem rather easy to identify. Likewise a person with known allergies knows whether or not he has allergic Conjunctivitis.

Treatment for infective Conjunctivitis that is caused by bacteria includes the application of antibiotic ointment or antibiotic drops. If it is caused by a virus, typically the condition is left to heal on its own, much like a cold. Generally however, it is difficult to determine whether infective Conjunctivitis has resulted from bacteria or a virus so oftentimes, no treatment is prescribed.

In either case it is important to wash hands after coming into contact with the infected eyes using warm water and soap. Those with infective Conjunctivitis should not share their towels or pillows with others. Also when Conjunctivitis is present, contact lenses should not be worn until it has cleared.

How does astigmatism affect your vision?

Eye Problems – Astigmatism

What is Astigmatism?

Astigmatism is a common eye problem in which a person's cornea or lens has an irregular shape. These problems are known as Corneal astigmatism and Lenticular astigmatism respectively.

The cornea is a clear layer that completely covers the part of the eye that has color. Ideally, the shape of the cornea is round, like a tennis ball. The cornea's job is to bend rays of light that enter the eye so that these light rays can be better focused on the lens enabling the retina to produce a clear image.

When the cornea has a more oval shape, like that of a football, light cannot focus properly. Instead of one focus point, as is what happens when the cornea is properly shaped, the misshapen cornea focuses light onto two areas of the retina. That is what results in blurred vision and/or the appearance of doubled vision.

Symptoms of Astigmatism

Blurred vision, 'ghosting' or images that are doubled are the most common symptoms of astigmatism. These types of vision problems occur at all distances. Fatigue, eye strain and frequent headaches are other symptoms that may indicate astigmatism.

Who is at risk?

The shape of the cornea can be affected by anything that causes the eyelids to exert excessive pressure on the cornea. Other risk factors for astigmatism include hereditary, poor posture and performing redundant and excessive amounts of up-close work. Those who are nearsighted or farsighted are also at higher risk of developing astigmatism. Other factors that can increase the appearance of astigmatism include head trauma or a cut, tear or scar on the cornea.

Keratoconus, a condition which over time causes the cornea to thin and take on a more cone shape can also cause astigmatism. This condition develops around puberty and affects more women than men. It's also caused by excessive rubbing of the eyes.

Finally, diabetics are at increased risk of developing astigmatism as elevated blood-sugar levels can cause the shape of the lens to change.

Early Detection/Treatment of this eye problem.

A routine eye exam is the easiest way to detect astigmatism. The eye doctor will do a number of tests to determine vision clarity. To determine how light rays focus on the retina the eye doctor can perform a refractive evaluation. Reading the eye chart is a good way to determine visual acuity. Checking eye muscle performance, eye coordination and eye focusing capability are also part of a routine eye exam and can all help determine the presence and degree of astigmatism. Astigmatism is measured in terms of diopters and ranges from mild to severe.

Since astigmatism is an eye condition and not an eye disease, it is highly treatable. Common treatment options include corrective eye glasses and (toric) contact lenses.

Surgical treatment options have been highly successful at correcting the shape of the cornea. Photorefractive Keratectomy or PKR uses laser beams to change the cornea's shape. LASIK surgery involves making small incisions on the sides of cornea using laser beams. With Radical Keratectomy, laser beam incisions are made into the cornea.

The link between allergies and eye problems.

Eye Problems – Allergies

When a person has an allergic reaction, the eyes frequently become affected. Eyes turn red, become itchy and irritated, and they can also become watery. Rubbing the eyes seems to offer comfort, but the reality is that rubbing eyes that are responding to an allergic reaction often compounds the discomfort.

What are Eye Allergies?

Most often, eye allergies accompany nasal allergies, but they can occur without involving the nose. Eye allergies are triggered when an allergen makes contact with the eyes. The mast cells, which are cells inside the eyes, release histamines and other chemicals and their release triggers symptoms including irritation and inflammation.

Conjunctivitis allergies are a specific category of allergies that affect the eyes. Conjunctivitis is generally triggered by an outdoor seasonal allergen such as ragweed or grass. Conjunctivitis allergies are also known as Hay Fever conjunctivitis.

Vernal Keratoconjunctivitis is seasonal in nature and primarily impacts children. With this form of eye allergy, the edges around the outside of the cornea are affected. Atopic Keratoconjunctivitis is similar with the difference being that it affects adults. It is a chronic condition and it's one that can cause the eyes to become scarred if not treated.

Symptoms of Allergies

When exposure to an allergen occurs, the body reacts by releasing histamines. Histamine release causes fluids to build up in the nasal cavity, sinuses and also on the surface of the eye as well as the insides of the eyelids. This release is also a source of significant irritation. In addition to irritation, the eyes may become red and watery, and the eyes and eyelids can become swollen. In addition to the visible symptoms, eye allergies may cause a feeling that something is stuck inside the eye or a feeling that the eye is being scratched. Vision can also become blurry or hazy or otherwise unclear.

Who is at risk?

Any person regardless of age can develop eye allergies.

Early detection/treatment of this eye problem

The most effective treatment for allergies is to stay away from those items that trigger allergic reactions. Many everyday cosmetics including mascara, eye liners and eye brow pencils and face creams can all trigger an allergic reaction. In some individuals, eye allergies can be caused by wearing contact lenses. Dust mites, mold and pet dander can also cause eye allergies.

When allergies are suspected, detection is the key to effective treatment. It's important to note what a person had been exposed to immediately before the allergic reaction occurred. Over time, patterns will become apparent. Once the culprit has been identified, steps should be taken to restrict exposure to the allergen.

Changing the brand of cosmetics and other personal care products can help as can discussing the possibility of obtaining a different contact lens prescription with your eye care professional.

In addition to these changes, over-the-counter antihistamines, decongestants and eye drops can all help alleviate the symptoms of eye allergies. If allergies are troublesome and/or persistent, it may be time to see an allergist who can recommend prescription medications and eye drops to treat the symptoms of eye allergies.

What Is Age Related Macular Degeneration?

Eye Problems – Age Related Macular Degeneration

What is Age Related Macular Degeneration?

As the name implies, Age Related Macular Degeneration (ARMD) is an eye disease that is primarily triggered by age. There are two types of ARMD, wet and dry. Either can affect one or both eyes. The dry form is more prevalent, occurring in 90% of the cases. It's slow to develop and vision loss is gradual, although not necessarily severe. The wet form is much more damaging, causing rapid and severe vision loss.

Even though vision loss is not complete, it is significant enough for an individual to be considered legally blind and for quality of life to be severely affected.

Vision loss is not total because ARMD affects the central vision, not the peripheral vision. When the macula is damaged, a person cannot create a clearly detailed image. Since the macula is in the center of the retina, central vision is affected. The macula is a group of nerve cells that utilize light to create and send images to the retina.

Symptoms of ARMD

Those affected by ARMD will notice a spot in their vision that is clearly indistinguishable. For example, when looking directly at an image of a person, legs and head will be clearly visible, but the body itself, the part right in the center of vision, will appear to be covered with an area that appears either empty or dark. Besides blurred vision, straight lines may seem wavy and a person may not be able to recognize images that should be familiar.

Who is at risk?

Age is a primary risk factor of ARMD, with the majority of the cases developing in individuals aged 60 and over. However, hereditary and the environment can also trigger the onset of the dry form of this eye disease. Females develop ARMD more often than men.

Free radicals cause much of the cell damage that occurs inside the retina therefore cigarette smoking and hypertension increase the risks of developing ARMD. Those who do not eat a nutritionally-balanced diet may also be at risk as they are not providing the body with the antioxidant protection it needs to inhibit the damage caused by free radicals.

Early Detection/Treatment of this eye problem

It's difficult to detect ARMD. The dry form is slow to develop, and generally develops only in one eye. The unaffected eye compensates for the damaged eye, so symptoms are not readily noticeable.

Yellow deposits called drusen on the retina can usually be observed during an eye exam. The eye chart and dilating the pupils are two methods of detection. When wet ARMD is suspected, the eye doctor will use an Amsler grid or fluorescein angiography.

Unfortunately, no treatment can restore this type of eye damage. Glasses will not help, but vision aids and counseling can help a person adjust to life with a reduced vision loss.

Laser eye surgery treatments and photodynamic therapy have had limited success on wet Age Related Macular Degeneration. Other treatment options such as medication and radiation are still being studied.

The proper wear of contact lenses.

How To Wear Contact Lenses

Contact lenses in decades past were hard, uncomfortable and prone to breaking or getting lost. None of that is true today, provided you use them properly.

The first step, obviously, is to get ones that are just right for you, after an exam by your eye care professional. He or she will write you a prescription, taking into account the wear characteristics you want, such as disposable, extended wear and more. Contemporary equipment and experience allow eye doctors to fit everyone with contacts that are individually perfect for them and that fit exactly.

Note that word 'exactly'. While certain lenses require a break in or adjustment period, they should not be uncomfortable for very long. RGP lenses, for example, are firmer than soft contacts. They will take a few days longer than soft lenses to feel right.

During that period, you're getting used to something that is new and your eyes are conforming to the lens and vice-versa. Soft lenses should feel comfortable within a day or two at most. You should adjust to any contact lens by the period described by your doctor. Any longer than that and it's time to take them back.

Before deciding that the lenses are not right for you, though, make sure you're using them correctly.

Toric lenses for example, used by those who have certain types of astigmatism, can only go in correctly one way. Because they combine multiple shapes to correct the condition, if they are rotated upside down, they won't fit right, nor correct your vision appropriately. Similar comments apply to bifocals or progressives, which are often designed to be worn only one way.

Further, for most people, contact lenses differ between left and right. Getting them backwards will, it should be obvious, not give you optimal correction. It should be obvious, but it isn't always. The reason is that your eyes may differ only by a small amount and other things can interfere with optimal vision, such as cloudiness on the lens from improper cleaning.

The solutions here are simple.

Make sure you clean your hands and the lens properly before use. Small contaminants make a big difference when it comes to something as carefully crafted as your contacts. Protein buildup and bacteria buildup are much more likely, much quicker on lenses that aren't prepared correctly.

Also, make sure you put them in correctly. With eyes that only differ a little, it's easy to get them backwards and not know it. Some designs simplify the issue by actually imprinting a tiny L and R on the lens. Others rely on you to see that the left and right are correct after they're inserted, and reverse them if they're not. Toric lenses make clear which way they are to go - follow that.

Wear according to designed use. That is, if you have daily wear lenses, don't treat them like extended wear models. Take them out before bed. If you fall asleep with the lenses in, even during the day, use eye drops and allow the eye to get moisturized before removing them. Ironically, closed eyelids during sleep can cause them to dry out, since you produce less tear solution then. Allow your eyes time to adjust.

Some soft lenses can accidentally flip inside out. But even single vision lenses are designed to only be worn one way. Before inserting, ensure they look like a slice of a sphere with no ridges. If there's a tiny lip, they likely have gotten turned inside out. Firmer lenses, such as RGP models, show this more prominently, but it should be visible on others, too. Yes, it can be hard to see without your contacts in. Have a pair of glasses handy or get used to feeling for the small ridge.

With proper care and use, your lenses should not be irritating. That can lead to eye health problems. If they bother you, consult your eye doctor and ensure that your prescription and practices are both what the doctor ordered.

Contact Lenses and How The Eye Works

Contact Lenses and How The Eye Works

The human visual system is both simple and complex. Complex, because there are so many parts that have to work together to make sight possible. Simple, because those parts and the process can really be explained without in-depth knowledge of anatomy and biology.

An ordinary glass lens, such as a magnifying glass, focuses the light that moves through it by bending the rays toward a focal point. That's the bright spot you see when you hold one over a newspaper, for example. Something similar happens when light enters the eye through an opening called the pupil, behind a clear protective portion called the cornea.

The pupil is surrounded by the iris, the colored portion of the eye. The pupil can narrow or widen to regulate the amount of light admitted, from as small as about 2mm to as much as approximately 8mm. The iris contains the muscles that change the diameter of the opening. Just behind the pupil is the lens, the part that focuses the light rays similar to the magnifying glass.

But there's an important difference between a magnifying glass and the eye. The magnifying glass's focal point is fixed. The eye, by contrast, contains muscles that help shape the lens and that shaping process performs a number of important tasks. Most importantly, it makes it possible for the focal point to change.

A camera lens is a good analogy. Because the camera lens contains multiple pieces of glass that can be moved by turning the barrel, objects at different distances can be brought into focus on the film. The muscles attached to the lens perform a similar function in order to focus light onto the retina, which is like the film.

Focused light rays strike the cells of the retina, the cones and rods. The names come from the shapes of the cells. The cones - 7 million cells in the central part of the retina, called the macula - are responsible for sharp, detailed vision and color vision. The approximately 100 million rods around them help us see in dim light and provide peripheral vision.

When those focused light rays hit the cells chemical reactions occur that stimulate the optic nerve attached to the back of the retina to produce electrical impulses. Those impulses are then transmitted to the visual cortex, the part of the brain that organizes them. Many parts of the brain cooperate to cause the mind to conclude: 'Ah, a car.' But the visual cortex does the initial heavy lifting.

When the parts and process of vision work correctly, you see sharp, colored entities out in the world. When things go wrong, the need for contact lenses or eye glasses arises.
